Optimization of the Beam Size at the Interaction Point of the Accelerator Test Facility 2 / Cilento, Vera (Universita del Sannio (IT)) ; Tomás, Rogelio (dir.) (CERN) ; Petracca, Stefania (dir.) (Università del Sannio)
A new era of discovery in particle physics has opened in November 2009 with the start-up of the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, in Geneva, Switzerland. The LHC, a circular proton-proton synchrotron, operates at the highest energies particle accelerators ever achieved. [...]

Slow Extraction of Charged Ion Pulses from the REXEBIS / Bidault, Niels (CERN) ; Rodriguez, Jose Alberto (CERN) ; Lozano, Miguel (CERN) ; Sadovich, Sergey (CERN)
The Isotope mass Separator On-Line DEvice (ISOLDE) facility located at CERN, produces and transports Radioactive Ion Beams (RIBs) at low or high energy through the REX/HIE-ISOLDE linear accelerator, for nuclear physics, astrophysics, solid-state physics and applied-physics purposes. Increasing the charge state of the ions is a prerequisite for efficient acceleration and is accomplished by an Electron Beam Ion Source (REXEBIS). [...]
